Plant Feed Classification And Role
- Oct 20, 2017 -

Plant feed is divided into roughage, green fodder, concentrate feed, tuberous tubers feed is deer often eat food.

Rough feed

Mainly include hay, straw (rattan, vine, vine, straw), leaves (foliage), bad slag, etc .; its characteristics are large, difficult to digest, available nutrients less dry matter in crude fiber Content of 18% or more. But its wide source, variety, yield, low prices, is the main source of deer winter season.

2. green fodder

Mainly include natural forage, artificial cultivation of pasture, leafy vegetables. Rhizome, green foliage, green cut corn, green cut soybeans and so on. Green feed moisture content is high, about 75% to 90%. Therefore, the green fodder heat content is low, per kilogram of green fodder digestion can only be between 300 and 600 kJ. As the green feed with juicy and tenderness, deer daily intake of up to 10 to 15 kg. Green protein content is high. The crude protein content of gramineous grass is 1.5% ~ 4.5%, but lysine is insufficient. The content of nitrogen-free extract in the dry matter of green fodder is 40% to 50% and the crude fiber does not exceed 30%. Vitamin E, vitamin C, vitamin K, niacin content is more, but vitamin B6 (pyridoxine), vitamin C, vitamin C, nicotinic acid, Few, lack of vitamin D. Many types of green fodder, are introduced several major green feed.

3. concentrate feed

Including grape seed (energy feed), soybean flour seed (protein feed) and its processing by-products. Gramineous feed refers to the dry matter in the dry matter content of less than 6%, crude protein content of less than 20% of the valley class, bran and so on, generally per kilogram of feed dry matter in the digestion energy 10.45 trillion Coke above. More than 2.54 MJ / kg of digestive energy feed is called high energy feed. Beans and oil crops Seed and its processing by-products also have the characteristics of energy feed, but because of high protein content, it is classified as protein feed. Protein feed refers to the dry matter in the dry matter content of less than 6%, while the crude protein content of more than 20% of the cake feed, leguminous seeds and some processing by-products.

4. tuberous tubers

(1) carrot

Carrots are deer farms in autumn, winter and spring good vitamins supplement feed. Carrots are nutritious, sweet and tasty, easy to digest. Carrot contains 81% to 92% of water, 1.2% of crude protein, 3.0% of starch, 8% to 14% of starch and carbohydrate, 8% to 13% of digestible nutrients. Protein content is more than other roots. Carrot in a lot of vitamin species, it contains more carotene, vitamin C and B vitamins. Carrot nutrient digestibility is high, protein digestibility of 73%, fat up to 77%, nitrogen-free extract up to 99%. The

(2) feed beet

Beet crops according to their roots in the dry matter and sugar content of how much can be roughly divided into sugar beet and feed beet two. Sugar beet sugar content, dry matter content of 20% to 22%, up to 25%, but the yield is low. Feed sugar beet production is high, but the dry matter content is low, only 5% to 11%. Low sugar content. Feed beet is a valuable juicy feed in autumn, winter and spring. It contains high sugar, inorganic salts and vitamins and other nutrients. The crude fiber content is low, easy to digest. All kinds of sugar beet contains nitrogen-free extract is mainly sugar, but also contains a small amount of starch and pectin substances. Because sugar beet contains a lot of sugar, so the root is generally not used as a feed but for sugar, its by-product beet residue can be used as deer feed. Beet is a biennial herb, is one of the main sugar crops in China, the first year of life is mainly vegetative growth in the hypertrophy of the roots to accumulate rich nutrients, the second year to reproductive growth, Flower powder forming seeds.
